The current HitTestResult methods are not using the (3d)
transformation aware routines. This can lead to an assertion
SVGRenderBase::mapLocalToContainer method.

Remove HitTestResult::boundingBox() as it is only used in
two places and conceptually doesn't belong into a HitTest
which is operating on points. Update the Qt and Win code
to determine the rect themselves in a (3d) transformation
fashion.

Change HitTestResult::imageRect to use the (3d) transformation
aware RenderBox::absoluteContentQuad to avoid running into
an assertion with SVG content.
